INSULATED SUPPORT FOR ELECTRICAL CONDUCTORS.

A lication fled Kay as,

To all whom it may concern:

Be it known that we, LOUIS 'S'ramnnaonn and GUY HILL, citizens of the United States, and residents, respectively, of the borough of Brooklyn, city and State of New York, and Washington, District of Columbia, have jointly invented certain new and useful Improvements inlnsulated Sup orts for Electrical Conductors, of which tiie following is a s ecification.

his application is in part a continuation of our prior application Serial No. 235,335, filed May 18, 1918, patented June 1st,'1920, No. 1,342,308.

Our invention relates particularly to insulated inductance coils for use with currents of high frequency and hi h potential, and is thus especially adapte for use in radio ap aratus.

One 0 the objects of our invention is to provide an inductance coil with an insulating support therefor, said coil being secured to the insulatin body in such manner as to have its free e ge ex osed upon both sides thereof, each free e e being electrically connected with each ot er.

Another object of our invention is to provide a mounting of insulating material for the inductance coil ,said coil being secured to the insulating body in such fashion as to be ex osedgupori both sides thereof and electrica y connected.

Another object of our invention is to provide a sim le efficient inductance coil for use for high requency, high tension currents, which 18 easy and inexpensive to manufacture, and which has high mechanical strength and high electrical efficiency.

Another object of our invention is to provide a simple efficient inductance coil for use with high frequency and high tension currents which is rovided with duplicate sides to the end t at either side may be used at will, thereby subserving easy illstallation.

Another object of our invention is to provide a simple and. eflicient inductance coil for use in any installation which may be desi ed where it is desired to make electrica connection upon either or both sides thereof. c

Other obgects will appear from the specification an claims.

1920. serial no. 884,950.

Referring to the drawin s in which the same reference character in icates the same part in the several views:

Fig, 1 is a plan view of a support for an inductance coil embodying our invention.

Fig. 2 is a section on line fr5' of Fig. 1, the coil being also shown in section.

Our invention herein shown and described may be applied to any convenient form of support, and we have shown as illustrative of the support a skeleton frame S of solid insulating material.

In the drawings we show an arrangement of metallic studs 30 on the insulating su port S which are used for mounting e spiral coils upon a supporting rod, tube, slab or sheet, or any other form of insulating support. As shown, the metallic studs are arranged to project in opposite directions but they are.- insulated from each other so that two coils can be mounted upon one support.

Our invention. has advanta s in-special cases as where a fixed coupling is designed or maximum inductance is required in a small space.

The metallic studs 30 are arranged with respect to each other so that the projecting ends are opposite each other and we have found that a convenient way to mount these studs in such a construction is to provide a stud which is longer than the thickness of the support and w ich penetrates the support so that the exposed ends project on both sides thereof. This arrangement is thus provided for the mounting of spiral coils and also when the insulating supports consist of rods, tubes, sheets or any other suitable form. When the metallic studs project through the insulating support the two conducting coils which are wound and supported therebetween, one on each side of the support, are arranged in parallel so as to pro-- vide for reater current carrying capacity. The coil 1s permanently secured in kerfs or slots in the ends of the rojecting studs by solder or any other suita le means; The

studs may be made of brass and are preferabl tinned after slotting, and the conductor is preferably of cop er.

' As illustrated, the meta pins or studs 30 are so formed with ridges and corrugations 40 that they are secured to the insulating material during the process of molding and are therefore molded to the supporting plate, rod, tube or slab.

The material used in the construction of the supporting plate may be of any suitable insulating material, but we prefer to use for that purpose the insulating material which is known in the art as Electrose. The strip from which the inductance coil is formed is made of metal or any suitable kind of metallic alloy.

As changes of construction could be made within the scope of our invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind'described, a support of insulating material, a series of metallic posts or studs insulated from each other and arranged in rows radially extending from a common center and molded to said support, the said posts or studs extending through and projectin from each side of said support, and an e ectric conductor of spiral formation mounted upon the projectin ends of said posts or studs.

2. 1% a device of the kind described, a support of insulating material, a series of metallic posts or studs insulated from each other and arranged in rows radially extending from a common center and secured to said support, the said posts or studs extending through and projecting from each side of said support, and a spiral electric conductor mounted upon the projecting ends of said osts or studs.

3. In a device of the kind described, a support of insulating material, a series or set of metallic studs secured to said support and extending through the same and projecting from each side thereof, and a spiral conducting coil secured to each set of said studs, one coil on each side of said support.

4. In a device of the kind described, a support of insulating material, a spiral inductance coil having a free operative edge upon a side of the support, conductive supports molded to the insulating support centrally thereof and extending therethrough and outwardly therefrom, an inductance coil secured to the said conductive supports on each side of the insulating support.

5. In a device of the kind described, a support of insulating material, a series of supports of conductive material molded thereto at intervals and extending radially thereof, the said conductive supports extending through and being exposed upon either side of the insulating sup ort, and a spiral inductance coil secure respectively to the exposed ends of the conductive supports.

In witness whereof I, LOUIS S'rnINBnnonR,

have hereunto set my hand at the borough of Uanhattan, cit and State of New York, this 21st day of h ay, 1920.
